MANUFACTURE OF INLAID LINOLEUM FLOOR-CLOTH.

SPECIFICATION forming part of Letters Patent No. 675,271, dated May 28, 1901.

Application filed March 8, 1899.

To all whom it may concern..-

Be it known that I, THOMAS J. FLYNN, residing in the city of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in theManufacture of Inlaid Linoleum Floor-Cloth, of which the following is a specification. v

Theprimary object ofthis invention is to produce an inlaid linoleum floor cloth in which the variously-colored tesserae or shapes required to form the design shall have a granite-like appearance and clearly-defined lines of division, forminga pattern of perfect sym' metry in contrast to the former irregular blending ofthe variously-colored shapes,from which an integral sheet of composition results. This end is attained by pressing granulated linoleum composition of the various colors required for the design in molds adapted for the independent formation of the shapes until such shapes are of perfect symmetryand of sufficient density tobe readily handled. These shapes are then transferred from the molds to the canvas or other. suitable back-'1 in g,upon which they are arranged and pressed in the patterns for which they are designed. The molded shapes have a degree ofsymmetry which insures their perfect registration in forming the design, and the final pressure employed for securing their attachment to the backing expands them sufficiently to form fine straight lines of juncture without blending. The character of each shape is seen before it is finally attached to the backing, and it may therefore be discarded if defective. The shapes are not so blended together when placed upon the backing as to be inseparable, and hence a defective shape may be removed and replaced. The mode of operation and apparatus employed are rapid and economical and are adapted for use with various forms of composition and with existing machines for the manufacture of inlaid linoleum floorcloth.

In the accompanying drawings, Figure 1 is a transverse sectional elevation illustrating the apparatus designed for the practice of my invention. Fig. 2 is a sectional plan View on the line a a of Fig. 1. Fig. 3 is a sectional Serial No. 708,169. (No model.)

elevation on the line b b of Fig. 1. Fig. 4 is a'perspective View of the product.

Referring to the drawings, the molding-box -1 contains a molding-frame 2, having its face divided into cells 3, and receives a plunger 4.

The inner sides of the molding-box and the walls of the molding-frame may be of the pyramidal form shown in order to insure a close -fit between them and to facilitate the with- The cells 3, of

drawal of the molding-frame. the outline required, are preferably formed by setting metal strips 5 in the face of the molding-frame. These strips 5 extend up "ward through the thickness of the tesserae required and have their edges slightly beveled to-permit the ready withdrawal of the tesserae from the cells 3 and to facilitate the construction of the design upon the backing. Straps .6 pass around the ends of the moldingframe downward movement within the molding-box l and with the bosses 11 for lifting the plunger and molding-frame from the molding-box. Brackets 12 and wheels 13, journaled therein, are placed upon the ends of the molding-box,

by means of which and the track 14 the molding-box l, molding-frame, and plunger 4 may be moved as a whole under a press for operating the mold. This press comprises the fixed head 15, secured in place by the columns 16, anchored in the foundation 17, and the movable platen 18, supported upon hydraulic jacks 19.

In the operation the molding-box 1, having the molding-frame 2 therein, is charged with linoleum composition, preferably in granulated form, the space between the top of the molding-frame and the top of the moldingboxconstituting a suitable measure for the exact quantity of composition required for filling the cells 3,when the tesserae are pressed to the density required. The plunger 4 is then placed in position upon the composition, the straps 6 being passed through the keepbosses upon the plunger.

ers 7 and the pins 9 inserted. These parts are then moved along the track 14: to the press, and when in position the hydraulic jacks 19 and the platen 18 force the moldingbox 1 upward, by which the head 15 of the press causes the plunger 4: to press the composition down level with the tops of the cells, thus consolidating the composition into tesserze. The jacks and platen then fall, the molding-box and its contents are withdrawn along the track, and the molding frame, shapes, and plungerare lifted out of the moldlug-box by a lifting device attached to the The plunger may now be removed and placed upon a second charge of differently colored composition which has been charged into the moldingbox upon a second molding-frame placed therein for forming different shapes. The shapes are arranged upon the backing in the form of the pattern by means of templets or otherwise and are consolidated by pressure.

Having thus described my invention, I claim-- 1. In the manufacture of inlaid fioorcloth, a molding-frame provided with a plurality of cells formed by metal strips fixed on the face thereof, said strips extending from said face a distance equal to the thickness of tesserze to be formed therein, and a plunger for pressing composition into said cells, said composition being thereby pressed to the form of tesserze, substantially as specified.

2. In the manufacture ofinlaid floor-cloth, a molding-frame having a plurality of cells formed by metal strips fixed on the face thereof, a plunger for pressing composition into said cells, and means for limiting the movement of said plunger relative to said cells so that a definite space is provided between the bottoms of said cells and said plunger, whereby said composition is pressed into uniform tesserae, substantially as specified.

3. In the manufacture of inlaid linoleum floor-cloth, a mold comprising a molding-box, a molding-frame having a plurality of cells integral with the face thereof within said molding-box and a plunger movable within said molding-box coacting with said cells for the formation of a plurality of independent tesserze, substantially as specified and for the purpose set forth.

4. In the manufacture of inlaid linoleum floor-cloth, a mold comprising a molding-box, a removable molding-frame seated within said molding-box, a series of uniform cells fixed upon the face of said molding-frame, and a plunger movable within said molding-box into contact with the tops of said cells, substantially as specified and for the purpose set forth.

5. I11 the manufacture of inlaid linoleum floor-cloth, a mold comprising a molding-box, a removable molding=frame seated within said molding-box, a series of uniform cells upon the face of said molding-frame, a plunger movable within said molding-box into contact with the tops of said cells, and a movable connection between said molding-frame and plunger, substantially as specified.

In testimony whereof I have hereunto affixed my signature in the presence of the subscribing witnesses.

THOMAS J. FLYNN.
